This issue could be addressed in PR #87

The tests are intended to be run non-interactively, and it appears the cmake file already links the OSMesa libraries. OSMesa is needed for -show-scene, so we always set it up with that, which I guess is why we haven't seen this issue. Looks like wb_command has a conditional to decide whether to link to OSMesa or openGL.
